Sirin Software vs Capgemini Engineering: overview
Sirin Software
Sirin Software, founded in 2014 and headquartered in Pompano Beach, Florida with R&D centers in Kyiv and Ivano-Frankivsk, Ukraine, works specifically with semiconductor companies and IoT product teams on SDKs, firmware, middleware, and driver development. What makes Sirin relevant for a technical buyer comparing wireless-protocol depth specifically is the breadth of named protocol stacks it works across — Wi-Fi, BLE, Matter, UWB, NFC, and LoRaWAN — combined with embedded OS coverage spanning Linux, Zephyr, FreeRTOS, and ThreadX, rather than one protocol done well and everything else avoided.
Capgemini Engineering
Capgemini Engineering traces to Altran Technologies, founded in 1982 in France, a major engineering and R&D consultancy that Capgemini acquired in 2019 and rebranded as Capgemini Engineering in 2021. Now employing an estimated 45,000-52,000 people worldwide from a Paris-region (Neuilly-sur-Seine) headquarters, electronics and embedded engineering represents one technical domain within an extremely broad engineering-and-innovation consulting portfolio. For a buyer specifically comparing rebranded legacy consultancies, the practical question is which pre-2019 Altran teams, processes, and client relationships remain intact inside the much larger Capgemini organizational structure — a question worth asking directly rather than inferring from the name change alone.

Sirin Software vs Capgemini Engineering: pros and cons
| Sirin Software | |
|---|---|
| + | Works directly with semiconductor companies on SDK and driver development, closer to the chip than typical downstream product-firmware shops |
| + | Named coverage across six distinct wireless protocols reduces the need to shop separately for each connectivity technology |
| + | US headquarters with Ukraine R&D centers balances client-facing accessibility with delivery cost efficiency |
| - | Small team (11-50, varying by source) limits capacity for programs with several parallel workstreams |
| - | No public pricing tiers or minimum engagement figures for pre-qualification |
| - | Multi-protocol breadth means depth in any one protocol may be shallower than a single-protocol specialist |
| Capgemini Engineering | |
|---|---|
| + | Extremely large global scale (45,000+ engineers) can absorb programs no boutique or mid-size firm could staff alone |
| + | Broad engineering domains beyond embedded (mechanical, systems, cloud) available under one contract for complex products |
| + | 40+ year engineering consulting heritage predating the 2019 Capgemini acquisition and 2021 rebrand |
| - | Rebranded from Altran in 2021 after the 2019 Capgemini acquisition — confirm directly which legacy Altran teams and processes remain intact inside the larger organization |
| - | Embedded/electronics engineering is one technical domain within an extremely broad portfolio, not a dedicated specialization |
| - | Scale and process overhead of a firm this size is a poor fit for small, fast-moving embedded projects |
